Efficient: You like to plan big epic rides? Then you'll need a versatile tool to save fuel. The fourstroke SF03 triple-butted aluminum frame is light and stiff, which makes this bike a very efficient climber

130 mm Advanced Pivot System (APS) travel gives you that extra bit of control on sustained descents, and added comfort for long days in the saddle.

The new speedfox comes in 5 sizes from XS to XL, ensuring that no one misses out on the adventure. Refer to geometry chart for details.

With BMC's Big Wheel Concept (BWC) 29er geometry, you can enjoy increased stability at high speeds and more confidence in technical terrain — without compromising on agility. Short chain stays, a long reach coupled with a short stem, a low bottom bracket and a slack head angle all work together to keep the bike stable and its rider confident on the roughest trails.

Big Wheel Concept

Our Big Wheel Concept geometries are dedicated to the 29er wheel size.

Simply incorporating bigger wheels does not by itself make a better bike, and we are convinced that the best bikes are made by taking advantage of large wheels and a deliberate geometry. For BMC, performance is not about the size, it’s about the details.

Agility - Short chain stays and stem combined with a low bottom bracket means the bike in not only efficient but also fun and lively.

Stability - Slacker than usual head angle combined with a long top and wide handlebars help you stay in control through the worst lines.


advanced pivot system

Unsurpassed power transmission, traction control, and comfort.

The ideal suspension system converts all of a rider's energy into forward propulsion, while at the same time absorbing impacts. Mechanically, these two goals are at odds with one another. But BMC's APS rear suspension satisfies these two goals by carefully calculating the pivot points of the rear suspension so that inertial force generated under acceleration is not misdirected into compressing the shock.

How is this accomplished? With APS the virtual pivot point is positioned so that constant chain tension is maintained for forward acceleration. As such, pedaling forces are used for forward propulsion with no loss of energy transfer in the suspension system. At the same time, the shock system ensures optimum rear wheel traction, guaranteeing that those pedaling forces are not only getting to the rear wheel, but to the ground, as well. The end result is a suspension system that provides extreme power transfer efficiency, uncanny traction, and excellent comfort.



System integration

natural born postmount

Brake mount is directly bolted to the rear triangle.

Direct assembly of the brake caliper to the frame with no need for an adapter means improved braking power transfer, especially under demanding conditions.
